Is Keratinocyte Growth Medium 3 simply Keratinocyte Growth Medium 2 without BPE?
No. Although both Keratinocyte Growth Medium 2 and Keratinocyte Growth Medium 3 are serum-free, they differ in more than just the presence or absence of Bovine Pituitary Extract (BPE).
Keratinocyte Growth Medium 2 contains BPE and is designed for the cultivation of epidermal keratinocytes. Keratinocyte Growth Medium 3 is specifically formulated to be BPE-free and features a different supplement composition.
As a result, simply omitting BPE from Keratinocyte Growth Medium 2 does not generate a medium equivalent to Keratinocyte Growth Medium 3.
Please note: Keratinocyte Growth Medium 3 offers a higher level of standardization by eliminating BPE and supports the expansion of fast‑proliferating, homogeneous keratinocyte cultures. However, according to PromoCell's media classification, it is not considered a "defined" medium.
